Program to Compute Shape Coordinates, Uniform X and Y, and Centroid
Size.Windows. Shape is a program
to compute Bookstein's Shape Coordinates from 2-dimensional coordinates
from a digitizer, TV etc. Shape coordinates are computed by rotating and
translating individual landmark configurations to a baseline, and scaling
them by the length of the baseline. The transformed coordinates of the
other landmarks serve as variables that represent the shape of each specimen
relative to this absolute reference orientation. Input file format is
that used by the Rohlf&Slice GRF program. Several output formats are provided
(GRF, NTSYSpc, and tpspline). Source code is also available. By Mauro
